We have found that when external users of Servicenow generate an email communcation to our support email address, it creates a new ticket on our ticketing system.
We did some digging, and the explanation essentially was that Servicenow does not reply in the same thread of emails.
With Servicenow being used as a CRM tool for some major businesses now, I would have thought that other Hubspot users would have come across similar issues.
We are currently having to manually merge tickets to ensure we have a complete timeline. Any help with this would be greatly appreciated.
